Undo / Redo

Summary

QuSheet’s undo/redo system is accessed with the Edit menu or the undo/redo tool strip buttons. Control Z and Control Y are not supported.

QuSheet tells you what it will undo or redo using the menu or, for the tool strip buttons, the status bar.

“Doing” rather than “Redoing” clears out the “redo” forward history in much the same way as that new forward navigation cleared out the old forward navigation history.

Not everything is undoable – only those actions which affect QuSheet’s final output are. Changes to display preferences such as column sizes are not.

QuSheet file generation is also not undoable. It is up to you to backup your files.

Hitting undo or redo not only un-does the last command (or re-does the last undone command), it also cancels whatever you were doing at the time. Beware.

Input fields and cells are colour coded using the “entry” colour to indicate to you that you are mid-edit so that you do not lose your edits inadvertently when you undo or redo.

An edit is accepted by QuSheet when you press enter or navigate away, assuming that the edit was not in error (in which case it is cancelled).

The Escape key cancels an edit.

When inputting a new row in a display table using the insertion row, the whole row is colour coded using the “entry” colour to show you that the *whole row* is mid-edit. Be careful about using Undo or Redo in these situations – you wont just cancel the last change you made to the insertion row, you’ll cancel the whole of the row insertion process.

Right-clicking on the insertion row inserts (and accepts into QuSheet) a new row before popping up a dialog box to allow you to create a new key item in-situ.

All of this is explained in the 4th level of Help (see Help) under Editting.

A: The number of commands kept in the undo stack is configurable to between 0 and 50 under Preferences > Resources.
